[0002] Accidents such as burns and scalds occur from time to time in daily life. The coating therapy drugs currently used to treat such wounds contain silver and zinc components. During the coating treatment process, due to the precipitation of silver and zinc metal ions, burns or scald wounds After curing, the skin pigmentation leaves the shortcoming of cicatrix; moreover, the existing coating treatment medicine of this type is ointment or cream, which is simply coated with medicine on the wound surface, and there is no complete isolation between the wound surface and the outside world. It is very susceptible to infection by external bacteria; although in the existing therapy, there are also doctors who use plastic film to wrap the wound to prevent bacterial infection.
